36 Green Composites from Natural Resources
bonding between olive pit powder and PLA. From a general point of view, this is the
main disadvantage encountered during the incorporation of natural lignocellulosic
materials into polymers. Therefore, suggestions to achieve better interfacial bond-
ing are reported in the literature. Tserki et al. (2006) suggested promoting olive
husk our/PBS interfacial adhesion by means of surface treatment, acetylation, and
propionylation, as well as the addition of maleic-grafted PBS as a compatibilizer.
Other alternatives were extensively depicted (Frisoni et al. 2001; Mahlberg et al.
1998) and are described in Section 2.2.3.
